To all whom it may concern:

do it known that l, ELI, (l. Snocnnr, a citizen of the United States, residing"; at Bland Patch, in the county oi Somerset and State of Pennsylvania, have invented certain new and useful. Improvements in Draft A ppliances, oi. which the'following is a lull clear, and exact description.

This invention relates to a draft applh ance or draw-bar to he used in connection with the l ordsons or otoer tractors, and has for its object to provide such a device which may be moved laterally .oi the tractor and thereby keep the line of tractioi; always in the center lineoil the plmv or other 'larm implement being drawn.

Another object oi: the invention is to provide such a device which is simple in arrangement and made comparatively "few parts, and one in which the force 0! the pull is applied to substantial parts-s oi the ap iiaratus rather than to the relatively weak operating mechanism.

tlther objects and advantages oi the device will. be apparent from the tollmving descri ption whentaken in comiection with the ac companying drawings, in which;

l igure 'l. is a plan view of a tractor with my device attached.

Figure is a section taken on line f2-2 iiq'ure 3 is a plan view oi my attachment pa y in section V Figure 4L is a rear view oi? the devicc partly in section; and,

l igure 5 is a 'lfii'agnlentary perspective view of the draw-bar.

Referring to the drawings more in detaili the numeral 1 designates a tractor to which my draft appliance, designated generally by the numeral 2., is applied. This appliance consists oil: a guide bar or member 3 having the laterally projecting neck 4.. provided with openings 5, by which the device is at tached to the tractor. V

The guide bar 3 is provided with a longitudinal. passage or channel 6 forming shoulders 7-7 and inwardly directed flanges 8.-8. Mounted in this channel for sliding movement thereinis the draft bar This bar is channeled as shown at 10, liig. 5, to provide shoulders 11, which abut the shoulders 7 of the guide member 3. One edge of the bar 9 is provided with teeth 12 to be engaged by the worm 13, which is mounted for rotation in a recess let in the neck 4. The worm 13 is formed with a gear wheel 15 with which is operatively con nected a chain 16 to be operated from the seat oi the tractor by wheel 1'? which is sup ported on bracket 17. The edge of the draw bar 9 opposite to the teeth 12 is pro vided with an extension 18 in which are termed the openings l9 by which it may be comm-acted to a plow or other implement or vehicle to be drawn.

in use should the tractor be working around a hill and slip an inch or more side ways the driver merely turns the wheel L7 in the proper direction and thereby shifts bar the proper amount so that the line oi traction will still remain. along the center line oi the apparatus being drawn. hlly draft appli cc is also useful when drawing vehicles around sharp curves, etc.

in accordanci-a with the patent statutes i have described what l now believe to be the best embodiment 0! my invent-imp but i do not wish to be understood thereby as limiting myself or the scope of the invention us many chan es and modifications they be made without de nirting 'l roni the spirit oi the i nventioin and all such. l aim to include in the scope of the appended claims.

llhat ll claim as new and desire to secure by llietters Patent is: i

l. lln a draft appliance, a guide bar bar ing a longitudinal slot therein providing shoulders, and a vertically extending opening with which a portion oi the slot conimunicales, an elongated draft bar located in said slot and engagingaid shoulders teeth 'lormed on one edge the draft bar, and a worn: in said. opening For cooperating with said teeth.

2. In a draft appliance, a guide bar made of cast metal and formed with a slot and a vertically extending opening, said slot being so shaped as to provide inwardly directed flanges and an elongated dira'l't bar located in said slot, said dratt bar being Formed with counters'lmk portions to receive said. flanges.

3. in a draft appliance, a guidiia bar made of cast metal, and formed with a slot and a verticnlly extending opening, said slot be- .ing so shaped as to provide inwardly directed flanges, an elongated dratt bar provided with countersunk portions engaged by said flanges, teeth on one edge o'l said draft bar, and a worm in said recess for en gaging the teeth.
